Hello, First, I am not so good at English I'm a beginner on PSOC, and i'm trying to make adc-filter-dac using CY8CKIT-030. Input signal is sin signal(1.5Vp-p,offset 1V,1kHz~20kHz). But there is no output signal. Please tell me what is mistake.

To upload a complete project, use Creator 3.0 -> File -Y Create Workspace Bundle(minimal) and then upload the resulting archive here, but DO NOT use google chrome, that will not work. Use ie or firefox instead.

There is an example project doing just that: CE58352. I could not find the code for that at the Cypress website, but only at Element14. Note that the project is for the -001 kit, so it might need some adjustments for the -030 kit (e.g. ports). Also, since its quite old (for Creator Beta5, from 2011), some components might have been changed inbetween).
